Properties of Addition in Math

Definition of Addition

• Addition is a mathematical operation that represents combining two or more values to get a total or a sum.
• It is denoted by the plus sign (+).

Properties of Addition

• Commutative Property: The order of the numbers being added does not change the result.
  • Example: 2 + 3 = 3 + 2
• Associative Property: The order in which numbers are added does not change the result.
  • Example: (2 + 3) + 4 = 2 + (3 + 4)
• Distributive Property: Addition can be distributed over subtraction.
  • Example: 2 + (3 - 1) = (2 + 3) - 1

Types of Addition

• Whole Number Addition: Adding whole numbers, resulting in a whole number sum.
• Fraction Addition: Adding fractions, resulting in a fraction sum.
• Decimal Addition: Adding decimals, resulting in a decimal sum.

Real-World Applications of Addition

• Counting money: Adding amounts of money together.
• Measuring ingredients: Adding quantities of ingredients for a recipe.
• Scores and statistics: Adding points, runs, or other scores in sports and games.

Key Concepts

• Addend: A number being added to another number.
• Sum: The result of adding two or more numbers.
• Regrouping: Rearranging numbers to make addition easier, often used in multi-digit addition.
